Audi's flagship A8 limo has now become a range in South Africa as the 4.2-litre petrol V8 has been joined by a diesel model.
This new version's potential claim to fame, among board members and government officials trying to appear 'green', is that it's the only V8 diesel in its segment.
Appearing to be a decent compromise between performance and emissions, the A8 4.2 TDI is good for 258kW at 4000rpm and a heady 800Nm of torque available between 1750 and 2750rpm - which Audi claims will get the aluminium-bodied brute from 0-100km/h in just 6.2 seconds.
Yet despite its briskness and size, the CO2 emissions figure is a not-too-bad 199 g/km from combined cycle fuel consumption of 7.6 litres per 100km. Audi also claims an urban consumption figure of 10.2 l/100km and a highway figure of 6.1.
This latest version of Audi's twin-turbo V8 diesel sends its power to all four wheels via an eight-speed Tiptronic gearbox. This model also counts Audi's sports differential torque vectoring system among its standard equipment.
